Replacing a Sony tv backlight strip is less about “brand matching” and more about exact electrical and mechanical matching. Two strips can look similar, yet fail quickly or not light at all if the LED voltage, LED count, lens type, length, or connector layout differs. This guide explains how to identify the correct strip for a Sony television, what parameters matter most, and how StarSharp supports stable supply and consistent build quality for TV backlight replacement and production needs.
Start with the most reliable identifiers, in this order:
Original strip code printed on the bar
The printed code is often the fastest path to an exact match because it ties to the LED layout, lens geometry, and connector placement.
TV model and screen size
Sony model names help narrow the family, but the same model line can have different backlight sets across batches.
Key physical dimensions
Length and width must match the mounting points and reflector channels. Even a small length mismatch can shift screw holes or diffuser alignment.
Electrical parameters
The most common mismatch is mixing 3V LED strips and 6V LED strips. If your driver and strip voltage do not match, you can get no backlight, uneven brightness, or shortened life.
Set configuration
Many TVs use a specific combination such as left and right pieces, or multiple bars per set. If the set count is wrong, you may end up with incomplete illumination.
StarSharp publishes model mapping and basic parameters for Sony strip sets so you can cross-check these items before ordering.
Use this as a starting point for matching. Final confirmation should still be done by checking the printed strip code and dimensions inside the TV.
| Sony TV model coverage | StarSharp strip model number | LEDs and LED voltage | Size length and width | Set information |
|---|---|---|---|---|
| KDL-65W855C, KDL-65W859C, KDL-65W805 | CX-65S03E01-3C774-0-C-6CR-0375-W | 8 LEDs, 3V | 715 x 12 | Light bar for 65 inch class |
| KLV-46R470A, KLV-46R479A, KLV-46R476A, plus several KDL-46R4xx variants | SVG460AB1-REV3-121121 | 6 LEDs, 3V | 452 x 12 | 12 pcs per set |
| KDL-32R430B | lnnotek 32lnch WXGA NDSOEM WA TYPE A REV0.0 | 8 LEDs, 3V | 591 x 15 | 2L plus 1R pcs per set |
The table data above is based on StarSharp’s Sony backlight strip listings and product parameter blocks.
Sony backlight systems are sensitive to small differences because the optical stack is tuned as a system.
Voltage mismatch changes current behavior
A 3V-per-diode strip and a 6V-per-diode strip are not interchangeable. Even if the connector fits, the driver output and protection behavior can cause flicker, dim output, or shutdown.
Lens shape affects uniformity and hotspots
Lens height and beam pattern influence how light spreads across the diffuser. A different lens design can create bright bands, corner shadows, or visible dotting.
LED count changes brightness distribution
Swapping a 6-LED bar for an 8-LED bar changes spacing and total luminous distribution. The panel may look uneven even if it lights.
Length and mounting tolerance matter
Backlight bars sit in tight channels. A different width can bend the strip, lifting lenses closer to the diffuser and creating pressure points.
For consistent results, treat the backlight strip as a specified component, not a generic LED bar.
When you are sourcing Sony-compatible backlight strips at scale, a repeatable checklist reduces returns and rework:
Confirm the printed strip model number from the removed bar
Confirm length and width with a caliper or ruler
Confirm LED count per bar and LED voltage type
Confirm left and right composition if the set is asymmetric
Confirm pieces per set and whether the set is complete for the TV
Confirm connector orientation and cable reach inside the chassis
If you can only access the TV label and not the internal strip, StarSharp’s model mapping and parameter notes help narrow down candidates before teardown.
For buyers who care about long-term consistency, supply continuity is just as important as the part number match. StarSharp positions itself as a dedicated TV backlight enterprise with:
About a decade of R&D, production, and sales experience
Annual production and sales capacity exceeding 26 million units
More than 5000 specifications and models, covering direct-lit and edge-lit strips
This scale matters when you need repeatable batches, stable lead times, and the ability to support multiple Sony model families without constant requalification.
To get an accurate quotation and reduce back-and-forth, prepare these details:
TV model name from the label
Strip printed code if available
One clear photo of the original strip and connector
Length and width measurement
Required set composition such as 12 pcs per set, or 2L plus 1R
If you are planning an OEM or ODM program for TV repair channels or regional distribution, standardizing this data pack per model helps keep fit accuracy high across repeat orders.
The right Sony TV backlight strip is defined by exact fit, exact voltage, and exact optical layout. Use the strip code, dimensions, LED count, and set configuration as your primary filters, then validate against known model mappings. With StarSharp’s broad catalog coverage and high-volume manufacturing capability, you can source Sony-compatible backlight strips with clearer parameters and a supply setup designed for consistent production and replenishment.
